Further, a blade shell half system comprising a transport system and a plurality of blade shell half parts and related methods are disclosed.
Description
Technical Field
The present disclosure relates to the field of handling wind turbine blade components. In particular, the present disclosure relates to a system for transporting and/or storing blade shell half parts and a method of handling (e.g. transporting and/or storing) wind turbine blade parts.
Background
Wind turbine blades for horizontal axis wind turbines that generate electricity from wind power can be quite large, and today may exceed 70 meters in length and 4 meters in width. Typically, the blade is made of a fibre-reinforced polymer material and comprises an upwind side shell part and a downwind side shell part. Due to the size and fragility of these large rotor blades, the blades may be damaged during transportation and during handling. Such damage may severely degrade the performance of the blade. Therefore, the blades need to be carefully packaged to ensure that they are not damaged.
However, due to the increasing length of modern wind turbine blades, it becomes more and more complex and expensive to transport the assembled blades. For the total cost of manufacturing, transporting and mounting the wind turbine blade on the rotor of the wind turbine blade, it is not uncommon for the transportation cost to be as high as 20%. Furthermore, some blades are transported to the installation site by different transport means, for example by truck, train and ship. Some of these transportation means may have limitations on large loads, maximum height, maximum width, maximum distance between transportation frames or supports, e.g. as specified by local regulations. Thus, there is a logistics problem of providing a transportation solution suitable for various transportation means.
Overall, there is a need to make the transport solution simpler, safer and cheaper. The prior art shows various solutions for transporting more than one rotor blade using a single container or other packaging system, which is a significant way to reduce the transportation costs. However, the above limitations and limitations may increase the difficulty of transporting multiple blades using the same packaging system.
It is therefore an object of the present invention to obtain a new method and system for storing and/or transporting a plurality of wind turbine blades which overcomes or ameliorates at least one of the disadvantages of the prior art or which provides a useful alternative.
Disclosure of Invention
Accordingly, a transportation system for transportation and/or storage of blade shell half parts of a wind turbine blade, the blade shell half parts each having a tip end and a root end, is provided, wherein the transportation system comprises a frame assembly comprising a first transportation frame and a first set of one or more separator elements. The first set of separator elements comprises a first primary separator element configured to separate a first blade shell half-section and a second blade shell half-section adjacent to the first blade shell half-section. The first and second blade shell half-parts may be separable such that the second blade shell half-part is at least partially stacked over the first blade shell half-part.
Also provided is a blade shell half-component system comprising a transport system as described herein and a plurality of blade shell half-components each having a tip end and a root end and comprising a first blade shell half-component and a second blade shell half-component, wherein the first blade shell half-component and the second blade shell half-component are stacked on a frame assembly of the transport system.
Furthermore, a method for transporting and/or storing a plurality of blade shell half parts is provided, the method comprising:
supporting the first blade shell half with a frame assembly comprising a first transport frame;
arranging a first primary separator element on a surface of the first blade shell half; and is
The second blade shell half-parts are stacked on the first main separator element.
The disclosed systems and methods enable more volume efficient transportation and/or storage of blade shell half parts for wind turbine blades. In particular, providing a reduced height transport frame for a given number of blade shell halves allows for a relatively easy handling of the transport frame. The present disclosure relates to transportation and/or storage of blade shell half parts that are not assembled into a wind turbine blade.
The blade shell half-parts extend from a root end to a tip end and comprise a root region, a transition region and an airfoil region. The transition region of the blade shell half comprises a shoulder defining a maximum chord line of the blade shell half.
The method and/or system advantageously involves transportation and storage, such as road transport, rail transport and/or sea transport, of the blade shell half parts, e.g. having a blade length of at least 40 meters, or at least 45 meters, or even at least 50 meters. The method and/or system are particularly suitable for handling blade shell halves by lifting. The blade shell halves may be pre-curved such that when assembled into a blade and mounted on a horizontal wind turbine in an unloaded state in a windward configuration, they will curve forward from the rotor plane such that the tip-to-tower clearance increases. The blade shell half-parts have a tip end and a root end, having an inner surface and an outer surface. The inner surface of the blade shell half parts is a surface which is not exposed to the environment when the blade shell half parts are assembled into a wind turbine blade. The outer surface of the blade shell half parts is the surface that is exposed to the environment when the blade shell half parts are assembled into a wind turbine blade.
The transport system comprises a frame assembly comprising at least a first transport frame. The frame assembly has a first end and a second end and extends along a longitudinal axis. The frame assembly may comprise a second transport frame and/or a third transport frame. The first transport frame may optionally be connected to the second transport frame in a detachable or hingedly connected manner. The second transport frame, if present, may optionally be connected to the third transport frame in a detachable or articulated connection. The detachable transport frame enables the transport system to be detached when not in use, i.e. the transport system can take up less space during return transport, whereas the hinged transport frame enables the frame assembly to be easily reconfigured, e.g. stacked, for a more convenient configuration for return transport, e.g. reduced length and slightly increased height.
The transport frame, such as the first transport frame and/or the second transport frame, has a first end and a second end. The transport frame, such as the first transport frame and/or the second transport frame, may comprise a frame body and at least one support element. The at least one support element comprises a first support element configured to support a surface of the blade shell half. The first support element may be configured to support an outer or inner surface of the blade shell half part, such as a root region and/or a transition region of the blade shell half part. The at least one support element may comprise a second support element and/or a third support element configured to support a surface of the blade shell half. The second support element and/or the third support element may be configured to support an outer or inner surface of the blade shell half part, such as a transition region and/or an airfoil region of the blade shell half part.
The frame assembly may comprise a first side wall and/or a second side wall. The side walls of the frame assembly increase the rigidity of the transportation system and may provide protection for the blade shell half parts. The side walls may optionally be connected to the frame body of the first transport frame in a detachable connection. The detachable connection of the side walls allows the transportation system to be detached when transporting/storing the blade shell half parts.
The frame assembly may include one or more support arms. The support arm may optionally be connected to the frame body of the first transport frame and/or the further transport frame in a detachably connected manner. The support arm may be extendable, e.g. telescopic. The support arm may be L-shaped with the short side mounted horizontally to the frame body, e.g. such that the long side of the support arm is substantially vertical (25 degrees from vertical). The detachable connection of the support arms allows the transportation system to be detached when transporting/storing the blade shell half parts. The support arms may be configured to prevent lateral displacement of the blade shell half parts during transportation. The support arms may be distributed longitudinally along a longitudinal axis of the frame assembly.
Thus, when the transportation system for supporting the blade shell half parts is not in use, reduced transportation and handling costs of the transportation system are provided.
The transport system comprises one or more sets of separator elements. A set of separator elements, such as a first set of separator elements, may comprise one or more separator elements, such as one, two, three, four, five, six or more separator elements. The transport system comprises a first set of separator elements comprising a first main separator element. The first set of separator elements may comprise a first stage separator element. The first set of separator elements may comprise a first tertiary separator element. The first set of separator elements may comprise a first quaternary separator element. The first set of separator elements may comprise a first five-stage separator element.
The first set of separator elements, or at least a portion thereof, may be configured such that at least a portion of the second blade shell half-part is received within the cavity of the first blade shell half-part. For example, the first main separator element may be configured such that a portion of the root region and/or the transition region of the second blade shell half-part is accommodated within a cavity of the root region of the first blade shell half-part. In one or more exemplary transport systems, the first main separator element may be configured such that a portion of the airfoil region of the second blade shell half-part is accommodated within a cavity of the root region and/or the transition region of the first blade shell half-part.
The separator element, or at least a portion thereof, may be made of a polymer. Suitable polymers include polyethylene, polypropylene, polyester, and polyurethane. The polymer may be a foamed polymer.
The separator element may comprise a convex or concave surface configured to contact the inner surface of the blade shell half. Furthermore, the separator element may comprise a convex or concave surface configured to contact an inner or outer surface of an adjacent blade shell half. For example, the first primary separator element may comprise a convex surface configured to contact an inner surface of the first vane housing half. In a transportation system for a first blade shell half having a downwardly facing inner surface, the first main separator element may comprise a concave surface configured to contact an outer surface of the first blade shell half. In one or more exemplary transportation systems, the first main separator element comprises a convex surface configured to contact an inner surface of the second blade shell half-section or a concave surface configured to contact an outer surface of the second blade shell half-section.
The first set of separator elements may be configured to separate a first blade shell half-section from a second blade shell half-section adjacent to the first blade shell half-section, e.g. such that an inner surface of the first blade shell half-section faces an outer surface of the second blade shell half-section. Of course, it should be noted that the blade shell half-parts may be stacked such that the outer surface of a first blade shell half-part faces the inner surface of a second blade shell half-part, e.g. in a configuration where the inner surfaces of the blade shell half-parts face downwards. Such a configuration may be useful when stacking blade shell halves of the same type.
The first set of separator elements may be configured to separate a first blade shell half-section from a second blade shell half-section adjacent to the first blade shell half-section, e.g. such that an inner surface of the first blade shell half-section faces an inner surface of the second blade shell half-section. Such a configuration may be useful for different types of blade shell halves.
The transport system may comprise a second set of one or more separator elements comprising a second main separator element configured to separate a second blade shell half-section and a third blade shell half-section adjacent to the second blade shell half-section.
The second set of separator elements may comprise a second stage separator element. The second set of separator elements may comprise a second tertiary separator element. The second set of separator elements may comprise a second quaternary separator element. The second set of separator elements may comprise a second five-stage separator element.
The second set of separator elements, or at least a portion thereof, may be configured such that at least a portion of the third blade shell half is received within the cavity of the second blade shell half. For example, the second main separator element may be configured such that a portion of the root region and/or the transition region of the third blade shell half-part is received within a cavity of the root region of the second blade shell half-part.
The second main separator element may comprise a convex surface configured to contact an inner surface of the second blade shell half-part. In a transportation system for a second blade shell half-part having a downwardly facing inner surface, the second main separator element may comprise a concave surface configured to contact an outer surface of the second blade shell half-part. In one or more exemplary transport systems, the second primary separator element comprises a convex surface configured to contact an inner surface of the third blade housing half part or a concave surface configured to contact an outer surface of the third blade housing half part.
The second set of separator elements may be configured to separate the second blade shell half-section from a third blade shell half-section adjacent to the second blade shell half-section, e.g. such that an inner surface of the second blade shell half-section faces an outer surface of the third blade shell half-section. Such a configuration may be useful when stacking blade shell halves of the same type.
The second set of separator elements may be configured to separate the second blade shell half-section from a third blade shell half-section adjacent to the second blade shell half-section, e.g. such that an inner surface of the second blade shell half-section faces an inner surface of the third blade shell half-section. Such a configuration may be useful for different types of blade shell halves.
The transport system may comprise at least three sets of separator elements, wherein each set of separator elements is configured to separate two adjacent blade shell half parts.
The transport system may comprise a third set of one or more separator elements comprising a third main separator element configured to separate a third blade shell half part and a fourth blade shell half part adjacent to the third blade shell half part.
The transport system may comprise a fourth set of one or more separator elements comprising a fourth main separator element configured to separate a fourth blade shell half and a fifth blade shell half adjacent to the fourth blade shell half.
The transport system may comprise a fifth set of one or more separator elements comprising a fifth main separator element configured to separate a fifth blade shell half and a sixth blade shell half adjacent to the fifth blade shell half. The transportation system comprising five sets of separator elements advantageously allows all blade shell half parts for a three-blade wind turbine to be stacked on the same frame assembly.
The blade shell half-component system comprises a plurality of blade shell half-components including a first blade shell half-component and a second blade shell half-component. The blade shell half may be one of two different types. The first type is an upwind side shell half-part (or pressure side shell half-part), i.e. configured to form the upwind side of the wind turbine blade. The second type is a downwind side shell half-part (or suction side shell half-part), i.e. configured to form the downwind side of the wind turbine blade. The blade shell half parts may be directed in a first direction, i.e. the root ends of the blade shell half parts are arranged near the first end of the frame assembly. The blade shell half parts may be directed in the second direction, i.e. the tips of the blade shell half parts are arranged near or at the first end of the frame assembly.
In one or more exemplary blade shell half-component systems, the separator elements of the first set of separator elements are distributed along the longitudinal axis between the root end and the tip end of the first blade shell half-component.
In one or more exemplary blade shell half-component systems, the first main separator element and the second main separator element at least partially overlap in the longitudinal direction. In other words, the first and second primary separator elements may be arranged at the same or substantially the same longitudinal position, or longitudinally aligned. In one or more exemplary blade shell half-component systems, the first and second stage separator elements at least partially overlap in the longitudinal direction. The overlapping separator elements prevent or at least reduce mechanical stress on the blade shell half parts arranged between the separator elements.
The first and second blade shell half-parts may be stacked or arranged in a root end to root arrangement, i.e. the first and second blade shell half-parts point in the same direction.
The first and second blade shell half-parts may be stacked or arranged in a root end to tip end arrangement, i.e. the first and second blade shell half-parts point in different directions (first or second direction).
In one or more exemplary blade shell half systems, all blade shell half may be arranged in an alternating root end to tip arrangement, i.e. adjacent blade shell half are pointing in different directions (first or second direction). In one or more exemplary blade shell half-part systems, the plurality of blade shell half-parts may be arranged in a combined root-to-root and root-to-tip arrangement, i.e. with adjacent blade shell half-parts pointing in different directions (first or second directions).
In a blade shell half system, at least a portion of a blade shell half may be accommodated within a cavity of an adjacent blade shell half.
The first blade shell half may be of a first type or a second type.
The second blade shell half-parts may be of a first type or a second type. The first and second blade shell half-parts may be the same type of blade shell half-part or different types of blade shell half-parts. The second blade shell half-part may be adjacent to the first blade shell half-part.
In a blade shell half system, at least a portion of the second blade shell half may be accommodated within a cavity of the first blade shell half. For example, a portion of the root region and/or the transition region of the second blade shell half-part may be accommodated within the root region cavity of the first blade shell half-part. In one or more exemplary blade shell half-part systems, a portion of an airfoil region of a second blade shell half-part may be received within a root region cavity of a first blade shell half-part.
The plurality of blade shell half parts may comprise at least three blade shell half parts of a first type and/or at least three blade shell half parts of a second type.
The plurality of vane housing halves may include a third vane housing half. The third blade housing half-part may be of the first type or the second type. The third blade shell half-section may be adjacent to the second blade shell half-section. In one or more exemplary blade shell half-member systems having second and third blade shell half-members, at least a portion of the third blade shell half-member may be received within a cavity of the second blade shell half-member. For example, a portion of the root region and/or transition region of the third blade shell half-part may be received within the root region cavity of the second blade shell half-part. In one or more exemplary blade shell half-member systems having second and third blade shell half-members, a portion of the airfoil region of the third blade shell half-member may be received within the root region cavity of the second blade shell half-member.
The plurality of blade shell half parts may comprise a fourth blade shell half part. The fourth blade shell half may be of the first type or of the second type. The fourth vane housing half can be adjacent to the third vane housing half. In one or more exemplary blade shell half-component systems having third and fourth blade shell half-components, at least a portion of the fourth blade shell half-component may be housed within a cavity of the third blade shell half-component. For example, a portion of the root region and/or the transition region of the fourth blade shell half-part may be accommodated within a root region cavity of the third blade shell half-part. In one or more exemplary blade shell half-component systems having third and fourth blade shell half-components, a portion of the airfoil region of the fourth blade shell half-component may be received within the root region cavity of the third blade shell half-component.
The plurality of blade shell half parts may comprise a fifth blade shell half part. The fifth blade shell half may be of the first type or of the second type. The fifth blade shell half may be adjacent to the fourth blade shell half.
The plurality of blade shell halves may include a sixth blade shell half. The sixth blade housing half may be of the first type or the second type. The sixth blade shell half may be adjacent to the fifth blade shell half.
In one or more exemplary blade shell half-part systems, the blade shell half-parts may be arranged such that an inner surface of a blade shell half-part faces an outer surface of an adjacent blade shell half-part. Thus, the first blade shell half-part may be arranged such that the inner surface of the first blade shell half-part faces the outer surface of the second blade shell half-part. Furthermore, the second blade shell half-part may be arranged such that an inner surface of the second blade shell half-part faces an outer surface of the third blade shell half-part. It may be advantageous if the second blade shell half-part and the third blade shell half-part are of the same type.
In one or more exemplary blade shell half-part systems, the blade shell half-parts may be arranged such that the inner surface of a blade shell half-part faces the inner surface of an adjacent blade shell half-part. Thus, the first blade shell half-section may be arranged such that the inner surface of the first blade shell half-section faces the inner surface of the second blade shell half-section. It may be advantageous if the first and second blade shell half-parts are arranged in a root end to tip end arrangement and/or are of different types.
In one or more exemplary blade shell half-part systems, the blade shell half-parts may be arranged at a longitudinal distance from adjacent blade shell half-parts pointing in the same direction. The longitudinal distance is measured along a longitudinal axis of the frame assembly. For example, in a root end to root end configuration, the second blade shell half-section may be arranged at a longitudinal distance from the first blade shell half-section. In other words, the first and second blade shell half-parts may be longitudinally movable.
In one or more exemplary blade shell half-part systems, one or more wind turbine blade assemblies, such as shear webs, may be arranged between two adjacent blade shell half-parts, such as between a first and a second blade shell half-part and/or between a third and a fourth blade shell half-part.
An exemplary blade shell half-part configuration (Emb 1, Emb 2, …, Emb 9) of the blade shell half-part system is shown in table 1 below, where T1 denotes that the blade shell half-part is of a first type (upwind side) and T2 denotes that the blade shell half-part is of a second type (downwind side). Furthermore, a denotes that the blade shell half parts are arranged with the outer surfaces facing downwards and pointing in a first direction, B denotes that the blade shell half parts are arranged with the outer surfaces facing downwards and pointing in a second direction, C denotes that the blade shell half parts are arranged with the inner surfaces facing downwards and pointing in the first direction, and D denotes that the blade shell half parts are arranged with the inner surfaces facing downwards and pointing in the second direction.

The invention relates to transportation and storage of blade shell halves for wind turbine blades of a Horizontal Axis Wind Turbine (HAWT).
Fig. 1 shows a conventional modern windward wind turbine according to the so-called "danish concept" with a tower 4, a nacelle 6 and a rotor with a substantially horizontal rotor shaft. The rotor comprises a hub 8 and three blades 10 extending radially from the hub 8, each blade having a blade root 16 closest to the hub and a blade tip 14 furthest from the hub 8. The rotor has a radius denoted by R.
FIG. 2 illustrates a schematic view of an exemplary wind turbine blade 10. The wind turbine blade 10 has the shape of a conventional wind turbine blade having a root end and a tip end and comprises: a root region 30 closest to the hub, a profiled or airfoil region 34 furthest away from the hub, and a transition region 32 between the root region 30 and the airfoil region 34. The blade 10 includes a leading edge 18 and a trailing edge 20, the leading edge 18 facing in the direction of rotation of the blade 10 and the trailing edge 20 facing in the opposite direction of the leading edge 18 when the blade is mounted on the hub.
The airfoil region 34 (also referred to as the profiled region) has an ideal or nearly ideal blade shape with respect to generating lift, while the root region 30 has a substantially circular or elliptical cross-section due to structural considerations, for example, making it easier and safer to mount the blade 10 to the hub. The diameter (or chord) of the root region 30 may be constant along the entire root region 30. The transition region 32 has a transition profile that gradually changes from the circular or elliptical shape of the root region 30 to the airfoil profile of the airfoil region 34. The chord length of the transition region 32 generally increases with increasing distance r from the hub. The airfoil region 34 has an airfoil profile with a chord extending between the leading edge 18 and the trailing edge 20 of the blade 10. Width of chord with distance from hubrIs increased byAnd decreases.
The shoulder 40 of the blade 10 is defined as the location where the blade 10 has its maximum chord length. Shoulder 40 is generally disposed at the boundary between transition region 32 and airfoil region 34.
It should be noted that chords of different sections of the blade typically do not lie in a common plane, as the blade may twist and/or bend (i.e. pre-bend), providing a chord plane with a correspondingly twisted and/or curved course, which is most often the case to compensate for the local velocity of the blade depending on the radius from the hub.
The wind turbine blade 10 comprises a shell made of fibre-reinforced polymer comprising two blade shell half parts and is typically manufactured as a pressure side or upwind side blade shell half part 24 and a suction side or downwind side blade shell half part 26 glued together along a bond line 28, wherein the bond line 28 extends along the trailing edge 20 and the leading edge 18 of the blade 10.
Fig. 3 and 4 depict parameters that may be used to explain the geometry of blade shell halves stored and transported according to the invention.
FIG. 3 shows a schematic view of an airfoil profile 50 of a typical blade of a wind turbine depicted with various parameters, which are generally used to define the geometry of the airfoil. The airfoil profile 50 has a pressure side 52 and a suction side 54, which in use, i.e. during rotation of the rotor, typically face a windward (or upwind) side and a leeward (or downwind) side, respectively. The airfoil 50 has a chord 60, the chord 60 having a chord length extending between the leading edge 56 and the trailing edge 58 of the bladec. The airfoil 50 has a thicknesstWhich is defined as the distance between the pressure side 52 and the suction side 54. Thickness of airfoiltVarying along chord 60. The deviation from the symmetrical profile is represented by the camber line 62, which camber line 62 is the median line through the airfoil profile 50. The centerline may be obtained by drawing an inscribed circle from the leading edge 56 to the trailing edge 58. The median line follows the center of these inscribed circles and the deviation or distance from the chord 60 is called the vault heightf. The asymmetry can also be defined by using parameters called the upper camber (or suction side camber) and the lower camber (or pressure side camber), whereThe upper camber and the lower camber are defined as the distances from the chord 60 to the suction side 54 and the pressure side 52, respectively.
The airfoil profile is typically characterized by the following parameters: chord lengthcMaximum arch heightfMaximum arch heightfPosition ofd f Maximum airfoil thicknesst(which is the maximum diameter of the inscribed circle along the median arch line 62), maximum thicknesstPosition ofd t And a nose radius (not shown). These parameters are generally defined as chord lengthscThe ratio of. Thus, local relative blade thicknesst/cGiven as the local maximum thicknesstWith local chord lengthcThe ratio of (a) to (b). In addition, the position of the maximum pressure side camberd p May be used as a design parameter, of course, the location of the maximum suction side camber may also be used as a design parameter.
Fig. 4 shows further geometric parameters of the blade and of the blade shell half-parts. The blades and blade shell halves having a total blade lengthL. As shown in fig. 3, the root end is in positionr= 0 and the tip is located atr=LTo (3). The shoulders 40 of the blade shell halves are in positionr=L w And has a shoulder widthWWherein the shoulder is wideWEqual to the chord length at the shoulder 40. The diameter of the root is defined asX. In addition, the blade/blade shell half is provided with a pre-bend, defined as Δ y, which corresponds to an out-of-plane yaw with respect to the pitch axis 22 of the blade.
Over time, the blades become longer and longer, and may now exceed 70 meters in length. In addition, the root diameter of the blade increases. The length of the blade, the root diameter and the shape, curvature and pre-curvature of the blade relative to the shoulder make it increasingly difficult to transport the blade, especially if a plurality of blades are to be transported and stored together. The shape and size of the blades also limits how closely the blades can be stored in a stacked array.

The blade shell half-component system 100 includes a transportation system 102 and a plurality of blade shell half-components including a first blade shell half-component 104, a second blade shell half-component 106, and an optional third blade shell half-component 108.
